The prototype was developed to meet strict requirements from the Australian Defence Force

A world-leading electric all-terrain vehicle (ATV) prototype providing enhanced stealth and manoeuvrability benefits for defence personnel has been developed by Melbourne-based electric vehicle conversion expert, EVolution Australia.
Featuring independent wheel drive with maximum torque from standstill via a unique and custom designed tri-motor drivetrain, the e-ATV prototype was developed to meet strict requirements, primarily reduced noise and heat signature to mitigate risk of discovery while in the field.
Individually powered wheels also enable greater manoeuvrability and an improved opportunity for moving away from threats, even if one wheel has been damaged by an Improvised Explosive Device (IED).
EVolution Australia worked with the Defence Science and Technology Group (DSTG) to plan, design and build the prototype vehicle, which Director, Russ Shepherd, said is an industry-leading outcome.
“The e-ATV has been a challenging and highly experimental project that fulfills the client brief of enhanced survivability, while providing insight into the decarbonisation and deployment of electric defence vehicles as the transition to low-emission transport gathers pace,” Russ said.
As independent wheel drive was unachievable with current hub motor technology, so the EVolution team designed a bespoke drive system utilising latest e-mobility componentry, with the aim of improving design over time.
“This was enormously challenging as this type of design doesn’t exist anywhere in the world. It’s been a completely unique process that adapts components and technology to a one-of-a-kind electric vehicle,” Russ said.

EVolution General Manager, Jack Puzin, said establishing strong supplier relationships had been integral to the success of the e-ATV.
“Due to the unique design, it’s been exciting to align ourselves with local partners who share our vision and jump completely on-board with the seemingly impossible, despite demanding timelines,” Jack said.
“In doing so, we preferenced Australian companies, but spoke to technology leaders all over the world to gather information. This enabled us to balance emobility technology with aesthetics and ergonomics, to deliver a driveable and fully-functional electric vehicle.”
Interestingly for the EVolution team, the e-ATV used a mix of specialist skills and knowledge that move away from that of a traditional automotive mechanical workshop.
“This future-focused project has highlighted to us the need to provide training and advice to the automotive sector, to prepare a new generation of e-mechanics,” Russ said.
“We’re extremely proud of this rewarding outcome. The e-ATV is by far the coolest project we’ve worked on and we’re very grateful to the DSTG for partnering with our leading Australian-owned conversion business in this exciting emerging sector.”
